STREET OR ROAD SNOWPLOW.

Application filed January 18, 1927. Serial No. 161,777.

of snow from roads or highways which shall,

embody therein, as a co-acting part, an automotive road vehiclewhichshall be of such construction that the component parts shall be readilyseparable to permit use of the vehicle for any purpose that is desiredand to enable conversion quickly and easily even by unskilled workmen ofthe vehicle, into a, snow plow when desired.

More specifically, the object of my invention is to detachably mount asnow plow on the front end of an automobile, saicl'snow plow havingcentrifugal fans in operative engagement with the crank shaft of theinternal combustion motor-of the automobile.

A still further object is to so construct my device that it may besecured to the front axle of an automobile whereby the snow plow will beguided by the steering wheel of the automobile.

A further objectis to so construct the plow ugal fans will be forced tothe side of the road independent of the fans, and also to so constructthe plowthat all snow entering the path of the fans will be inbroken andloose condition.

to those skilled in the art.

My invention consists in the constructlon,

arrangement and combination of the various.

parts of the device, whereby the objects contemplated are attained ashereinafter more fully set forth, ointed out in my claims andillustrated in t e accompanying drawings, inwhich: K

Figure 1 is a top plan view of my snow foruse.

Figure 2 is a side elevation of my com plete device installed on anautomobile.

Figure 3. is a rear sectional view of 'my snow plow taken on line 3-3 ofFigure 2. A section of the device is cutaway to more successfullyillustrate .the mechanism for driving the two centrifugal fans.

I have designated the ordinary automobile by the numeral 10. I have usedthe numerals 11 and 12 to designate the frame of my snow plow. Themembers 11 and 12 are pivotally secured to the members 13 and 14respectively, which are designed to be secured to the front axle 15 ofthe automobile by U bolts 16. The forward ends of the members 11 and 12extend downwardly and outwardly and terminate a slight distance abovethe roadway. Secured to these memhers is my two-way snow plow or shovel17.

The numerals 18 and 19 designate braces for more securely holding theplow or shovel 17 in'proper position. On each side of the center line ofthe shovel 17 is an opening 20 and 21, back of each is a centrifugal fanhousing 22 and 23. Each of the fan housings 22 and 23 have an outlet ipe24'and 25 extending upwardly. Rotatably mounted upon each of theseoutlet pipes 24 and 25 and communicating with each respectively is adistributing pipe 26 and 27 of L construction. Thus it will readily beseen that by turning the distributing pipes, the snow passing therefrom,may be deposited in any desired location relative to the travel of theautomobile. Rotatably mounted in each of the centrifugal fan housings ina centrifugal fail 28 and 29. The numeral 30 designates a gear housingposition directly back of the two fan housings. Rotatably mounted in thetwo bearing members 31 and 32 secured to the housing 30, is a shaft 33.Secured to one end of the shaft 33 against relative rotation is a bevelgear 34 in operative engagement with the bevel gear 35 which is per-These and other objects will be' apparent shaft 36 of the centrifugalfan 28.

manently secured to the centrifu al fanecured to the opposite end of theshaft 33 against relative rotation is the bevel gear 37 in operativeengagement with the bevel gear 38 which is permanently secured to thecentrifugal fan shaft 39 of the centrifugal fan 29.

It will readily be seen by those skilled in the art that if the shaft 33is rotated, the two centrifugal fans will also be rotated in theirrespective housings and that if snow entered the openings 20 and 21 itwould be forced 'out of the'cdistributing pipes 26 and 27. I have usedthe numeral 40 to designate a.

sleeve member capable of embracing the crank shaft 41 of the internalcombustion engine and having notches 42 capable of engaging the crankshaft pin 43.. Secured to this sleeve 40 is the drive shaft 44 rotatablymounted on a bearing member 4C5 which is cured at its opposite -end i onthe crank shaft 41 by the spring 55.

- i other purpose desired.

frame of the plow being pivotally will not be thrown over 'tendingflange 56 supported by the hand crank guide case 46 of the automobile.Secured to the forward end of this shaft 44 is a universal joint 47. Thedrive shaft 48 leading from this joint is square at its forward end andenters and is capable of sliding movement in a square hole in the hollowdrive shaft 49 which is se-' to. the universal joint 50. The numeral 51designates a fourth drive sal joint 50, journaled near its forward endin the bearing members 52 and 52' and extending within the housing 30.Permanently secured to the free end of this shaft 51 is the bevel gear53 in operative engagement with the bevel gear 54 permanently secured tothe shaft 53. By this arrangement when the internal combustion motor isrunning, both of the centrifugal fans will berotating at a speedrelative to the speed of the motor. This is ver advantageous due to thefact that when t e snow is very bad and a great amount of it is to behandled, the car must travel in either low or intermediate ear and thecentrifugal fanswill thereby be rotating very fast and will be able totake care of the greater amount of snow; By the to the front axle thevariations of the road bed are compensated for. It is because of thisconstruction-that it is necessary for the shafts 48 and 49 to slide onewithin the other. The universal joints 47 and also help compensatefurther changing of the position of the snow plow relative to that ofthe automobile. as follows: 13 and 14 to the axle 15 by the U bolts 16.sleeve 40 onto the crank shaft 41 in. order that the notches 42 thereinw'll engage the pin 43. -This sleeve 40 is yieldingly l llt llld ecomplete device is now ready for use. merel ne'cessar to remove the Ubolts 16 and t e low will be disconnected from the automobi e whichmaythen be used for any.

It will readily be appreciated that my apparatus is simple inconstruction and operation and is of-durable construction and is of suchcharacter as will admit of operation by any person capable of driving amotor vehicle.

It is apparent that some changes may be made in construct-ion andarrangement of my device without construction also aidsv departing fromthe real spirit and purpose of my invention, and it is my intention tocover by my claims any modified forms of structure or use of mechanica-luivalents which maybe reasonably inclu ed within their scope.
